1977 Gmc Sierra, Lost Key?

[Nathan]

I have a 77 sierra in which I lost the key. Its a junker but we use it for work. I don't want to pay hundreds of dollars to replace the ignition to figured I could try and rewire the ignition using a switch to start the truck. Can anybody help me identify the wires in this truck to rewire the ignition. Thanks

once you get it hotwired, how do you turn the steering wheel? call a locksmith and do the job right, it shouldn't cost more than $75.00 or so
